CSA INTERNATIONAL: In the U.S., CSA International is accredited by the Occupational Safety and Health Administration (OSHA) as a Nationally Recognized Testing Laboratory (NRTL).

OSHA accredited laboratories are certified to conduct tests against the same sets of U.S. standards and codes, regardless of who authors or publishes them. For example, CSA International tests to applicable U.S. standards, including ANSI, UL, CSA, NSF, and others.

CSA International is also accredited in the international CB Scheme for testing to IEC standards and can help obtain the CE marking in Europe.

The RoHS directive aims to restrict certain hazardous substances commonly used in electronic equipment. Any RoHS compliant component is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance.
